Recommend performing condenser coil cleaning. The system has Tripp the high pressure switch. This is due to dirty condenser coils. Cleaning cannot be performed until peco removes the box they have attached to the side panel. See photos. Performed condenser coil cleaning for a Lennox system. Turned power off to the system and removed all side panels. Cleaned coils using proper chemical solution. Re installed the side panels and turned the power back on. I observed the system starting normally.the system is operating properly at this time.
